As one of the three main algal communities associated with polar sea ice, the occurrence of a sub-ice community has been recorded during a May 2012 field campaign conducted in the central Canadian High Arctic around Cornwallis Island, Nunavut. The sub-ice community was only observed once at the nearshore station in Wellington Channel (water depth: 85 m; ice thickness: 1.3 m; snow depth:<4 cm), forming short strands< 10–15 cm in length. The community was dominated by the northern cold water centric diatom,Melosira arcticaDickie, which formed very dense aggregates of several parallel, vertically aligned chains of cells, held tightly together by a secretion of mucilage from the rimoportulae on the valve face within the limit of the carina. In addition, three epiphytic diatom taxa were present,Chaetocerossp.,Synedropsis hyperborea(Grunow) Hasle, Medlin & Syvertsen andPseudogomphonema arcticum(Grunow) Medlin. Surprisingly, and in addition to these epiphytes, some raphe-bearing diatoms were also part of this sub-ice community, gliding over the colonial filamentous cells ofM. arctica.
